Neotropical Bird Migration During The Ice Ages: Orientation And Ecology [PDF]

open access: yes, 1996
Reconstruction of breeding habitat of North American Neotropical migrants 18,000 years ago and 9,000 years ago indicated major shifts in both location and composition of plant communities relative to present conditions.

Drought and Herbivory Have Selective Transgenerational Effects on Soybean Eco‐Physiology, Defence and Fitness

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Soybeans, one of the most important legumes, face multiple stresses including drought and herbivory. But the potential transfer of the interactive effects of these stressors onto the transgenerational plants has not been understood. We hypothesised that progeny from stressed parents will have enhanced ecophysiology and defence traits through ...

Dietary Spirulina platensis mitigates fenitrothion-induced growth retardation, hematotoxicity and immune-oxidative stress in striped catfish

open access: yesJournal of Agriculture and Food Research
Fenitrothion is a commonly used pesticide to eradicate pests in aquaculture ponds. However, it exerts toxic effects on non-target biota, including fish. The microalga (Spirulina platensis) may alleviate fenitrothion-mediated toxicity in fish.

High throughput phenotyping method for water use efficiency in rice under field conditions : [Abstract, P 6.04] [PDF]

open access: yes, 2009
A collaborative CIAT/Cirad project aims to create new improved upland rice germplasm for drought tolerance based on population improvement through recurrent selection (RS).

Physiological drought responses improve predictions of live fuel moisture dynamics in a Mediterranean forest. [PDF]

open access: yes, 2018
The moisture content of live fuels is an important determinant of forest flammability. Current approaches for modelling live fuel moisture content typically focus on the use of drought indices.

De‐Coupled Water and Nitrogen Translocation From Subsoil to Canopy of Temperate Forest Trees

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Water and nitrogen (N) transport from soil to canopy play a central role in tree functioning, yet direct evidence for their timing and coupling in mature forests remains scarce. We report results from a paired dual‐isotope (2H, 15N) tracer experiment in a temperate forest, comparing water and nitrate uptake patterns across tree species ...

Ecology and ecophysiology of subantarctic Campbell Island megaherbs : a thesis presented in partial fulfilment of the requirements for the degree of Masters of Science in Ecology at Massey University [PDF]

open access: yes, 2000
The megaherb growth form is not common in the New Zealand flora; yet it is a distinctive feature of the flora of New Zealand's subantarctic islands, such as Campbell Island (52°33'S. 169°09'E).

Effects of Planting Density and Nitrogen Management on Light and Nitrogen Resource Utilization Efficiency and Yield of Summer Maize in the Sichuan Hilly Region

open access: yesAgronomy
The low efficiency of light and nitrogen resources, poor yield and profit, and environmental pollution of maize production are main problems in many areas of China.

Evaluation of maize and hemp cultivars as bioenergy crop [PDF]

open access: yes, 2010
We are cultivating annual and perennial crops as monoculture and as mixed culture to investigate plant biomass use for production of renewable energy sources in northern latitudes. We have grown different hemp (Cannabis sativa L.) and bioenergy maize (

Divergent drivers of leaf trait variation within species, among species, and among functional groups. [PDF]

open access: yes, 2018
Understanding variation in leaf functional traits-including rates of photosynthesis and respiration and concentrations of nitrogen and phosphorus-is a fundamental challenge in plant ecophysiology. When expressed per unit leaf area, these traits typically
